Data line protection
Doc ID 14310 Rev 3
13/42
If we consider the +25 kV air discharge surge test, then, regarding the suggested
application given in Figure 16: the worked example below may be used as a guideline for
protection solution selection.
Figure 16.
ISO 10605 ESD test set-up
Identification of the best protection (Transil)
About the module to protect:
●
The protection shall be “transparent” for the normal operating conditions of the module,
in this case 13.5 V.
●
The maximum voltage the module can withstand is 45 V so the Transil will not offer a
higher voltage than 45 V when acting.
●
The max temperature is 85 °C.
About the surge to suppress:
●
The maximum voltage (Vpp) of the surge is 25 kV.
●
The surge time constant duration
 is 660 ns (R*C).
●
The maximum repetition is one strike (t1).
●
The internal series resistor of the generator is 2 k
.
About the Transil:
●
The suppressor has the following electrical characteristics (Figure 17):

Where:
Vrm is the stand-off voltage measured @Irm. This corresponds to the nominal voltage of the
application Vrm13.5 V.
